TRANSOM-OPERATOR.

Specification of Letters Patent.

Patented Apr. 14., 1914;.

Application filed March 13, 1913. Serial No. 753,953.

To all whom it may concern:

Be it known that I, LOUIS B. SMYsnR, a citizen of the United States,residing at New BritaimHartford county, State of Connecticut, haveinvented certain new and useful Improvements in Transom Operators, ofwhich the following is a full, clear, and exact description.

This invention relates to operating means for transoins and alliedclosures, and is designed to provide a device of this character with arelative arrangement of parts affording greatest operating power at theperiod of greatest load; toprovide an assembled operating unit ready forattachment; and

further, to provide improved features of construction in connectlon withthe operating mechanism. These and other advan tages will be more fullydescribed in the following detailed specification taken in connectionwith the accompanying drawings forming part thereof and illustrating apreferable embodiment of the invention.

In these drawings: Figure 1 is a fragmentary view in side elevation fromthe outer face of a door jamb showing the operating mechanism appliedthereto and connected to a transom. Fig. 2 is a front elevation, partlyin section, of the parts shown in Fig. 1. Fig. 3 is a fragmentary viewin side elevation 011 an enlarged scale, of the parts shown in Fig. 1with the transom and its operating parts in closed position. Figs. 4: to7 inclusive are views on an enlarged scale of details of construction ofthe operating mechanism. Fig. 8 is a view in elevation and on anenlarged scale of the transom operating bar and gear case. Fig. 9 is anend elevation of the same partly in section. Fig. 10 is a view inelevation of the transom operating bar and gear case, the latter brokenaway and in section to disclose the interior arrangement. Figs. 11 and12 are views of details of construction of the gearing. Fig. 13 is asectional view through a door casing illustrating the position of theframe and gear casing therein.

As I have before stated, one of the objects of the present invention isto provide a unit construction whereby the operating parts may beapplied as an assembled unit. These operating parts, or such as arecapable of assembly prior to the application thereof to a door casing,are to be mounted on a frame or carrier preferably 111 the form of ametal bar or plate 1 extending vertically of the door edge and appliedto the outer face of the door jamb 2, or to that face which isnon-adjacent the door.

3 designates a transom of the bottom lunged type, the hinging meansbeing designated at a. The end face of this transom at a pointintermediate its top and bottom is provided with a plate 5 fixedlysecured thereto and provided with a longitudinal slot 6.

7 designates a transom arm having a stud 8 at its upper end seating inthe slot 6 of the transom'plate. The lower end of -this arm is providedwith two or more segmental slots 9 therein. This arm 7 is located on thetransom and door side of the jamb 2. On the opposite or outside face ofthe jamb is located a second arm 10 having a stud 11 secured to one endand carrying an anti-friction roller 12, and at its opposite endprovided with segmental slots 13. The frame 1. and jamb 2 are bored toprovide an opening through which a connecting stud 14 for these two arms7 and 10 may extend, this stud being provided at its opposite ends withsegmental. projections 15 designed to fit into the segmental apertures 9and 13 in these arms to rigidly connect them together. The arms arelocked by means of a screw extending through a longitudinal bore in thestud and threaded into the arm 10 between its slots 18. The head of thescrew seats in a countersunk recess in the arm 7 between its slots 9.These arms are connected at an acute angle and together form a leverdesigned, when force is applied to the free end of the arm 10 thereof,to move the transom 3 into and out of closed position. These operatingparts for the transom which I have described are separate from the frame1 carrying the operating mechanism and are attached to the transomindependently thereof, the door jamb, of course, being provided with abore through which the stud 14 extends, and a bushing 16 beingpreferably provided in this bore. The frame 1 is provided with anaperture therein through which the bushing and stud may extend, thelength of these parts being such as to space the face of the arm 10 fromthe face of the frame 1.

The operating unit,'of which the plate 1 forms the bed or frame, isdesigned as follows: A plurality of spaced and alined brackets 17 areprovided, these brackets being rigidly secured to the frame 1 by anysuitable means and being apertured to guide therethrough an operatingbar 18 extending vertically of the door jamb and longitudinally of theframe 1. Adjacent its upper end, this operating bar has fixedly attachedthereto a sleeve 19. Adjacent its upper end, the frame 1 carries abell-crank lever 20, one end being pivotally mounted on said frame bysuitable means as by a stove bolt 21, or similar means, which may extendthrough an aperture formed in the frame 1 and through a bore in the doorjamb 2, thus serving also to connect the upper end of the frame to thedoor j amb, although other or additional means may be employed to effectthis result, if desired. 22 designates a link pivotally connecting theother end of the bell-crank to the fixed sleeve 19 of the operating bar18. This bell-crank is designed to operate the transom through the arm10 connected thereto. As shown, the bell crank is provided with anelongated slot 23 therein, this slot extending between the pivot point21 of the bell-crank and the apex of its angle. A strengthening boss 24:is preferably formed about this slot. The anti-friction roller 12 of thearm 10 is designed to rest within the slot, the arm 10 being mounted toposition its roller at the lower end of this slot when the transom is inits lowered position so as to afford maximum leverage through thebell-crank lever 20 to raise the transom to closed from opened position,this maximum leverage being available at the time of maximum load orwhen the transom has been opened.

It will be evident that by moving the operating bar upwardly anddownwardly, the bell-crank 20 will be swung on its pivot to swing thetransom to and from closed position through the connecting lever formedby the arms 7 and 10 and pivoted eccentrically relative to thebell-crank so that the movement of the bell-crank on its pivot willswing this lever to effect the result named. In order to move thisoperating bar 18, its lower end is formed as a rack 25 and a gear casing26 is provided through which this rack end of the bar is guided, thisgear case being secured to the frame 1 by means of stove bolts 27 whichextend through apertures formed in the frame 1 and through bores formedin the door jamb 2, and serve also to connect the lower end of the frame1 to the jamb. These bolts extend out of and are accessible from thedoor side of the jamb, as will be clearly seen from the drawings. Thegear casing is provided with a cover 28 including gear housings 29 and30. A rack-engaging gear wheel 31 is seated in the base of the gearcasing and is provided with an integral sleeve 32 and with bosses 33formed at opposite ends of ing its head seated in a recess formed in theside of the housing and having a threaded end threaded into the housing29 and engaged at its projecting end by a nut 38 by means of which it isheld stationary within the gear housing. This bolt serves as a spindleon which is journaled a compound gear element comprising a sleeve 39having a worm 40 cut thereon positioned to engage with the annular wormgear at of the rackengaging gear element heretofore described. At itsoppositeend', the sleeve 39 is provided with a spur gear wheel 41positioned in the lower portion of the housing 30.

The gear housing 30 is separatefrom the" housing 29 and cover 28 of thegear casing and is held thereto by means of the bolt 37.

and by the provision of'an outward ofiset 42 in the cover 28, whichoffset part 1s'provided with a toothed upper edgeengaging with thetoothed lower edge 13 of the hous ing 30. Within the upper portion ofthe housing 30 is journaled a second gear wheel 14 in mesh with the gear&1 in thelower portion of the casing 30, this gear 4 1 being suitablyjournaled within the housing 30 and having a hub 45 extending through abore in the casing 30 and provided with'a squared aperture 46'therein.

Referring specifically to Fig. 13 of the drawings, it will be seen thatthe frame 1 is mounted upon the inside of the door jamb and that thegear case and its housings rest against the adjacent buck 47 which maybe recessed to receive these gear housings. The space between the buckand jamb. is, of course, covered by the usual strip of trim or molding18. It is through the gear 1 1- that motion is transmitted to therack-engaging gear wheel 31 and through the rack of the operating bar tothe transom. The appearance of the attachment is improved if theoperating handle, hereinafter described, which engages the squaredaperture 46 of the hub 45, is centrally positioned with reference to themolding 4:8. This is possible by reason of the fact that the housing 30may be vVhen the hub 45 has been properly positioned relatively tomolding l8, the housing 30 is pushed in to engage its toothed edge 13with the teeth of the offset 12, and the bolt 37 then screwed in and itsnut tightened.

It is further desirable to provide means for lubricating the parts ofthe gearing which are not easily accessible. In the specific form ofgearing disclosed herein, such parts will beparticularly the gearelement 40 and 3-4, the lubricant being distributed from these elements"to the other gear elements. To this end I provide a borein the door jamb2 in alinement with the boss 33 of gear 31 through which boss, gear andits sleeve 32 the lubricating aperture 35 extends, and insert into saidbore in the boss 33, an oiling tube 49, to the outer end of which issecured a valve casing 50 having in its outer end a lubricant inletopening 51 normally closed by a ball valve 52 pressed thereagainst by acoiled spring 53. The outer end of this valved inlet to the lubrieatingtube is positioned at the door side of the jamb 2,"preferably slightlywithin the edge of the jamb so that access may be readily had theretofor the purposes of lubrieating the gearing.

The molding strip48 is, of course, provided with a'suitably located borethrough which the spindle 54: of an operating handle I 55 extends, asuitable rose 56 being preferably provided and resting against the outerface of the molding 4:8. The inner end of the spindle 54 is squared andseats in the squared socket 46 of the hub of gear 14: so that when thehandle is turned from the exterior, the worm gearing 34L40 is operatedthrough gear. train 4H1, operating the rack and pinion gearing 2-5-81 toraise or lower the operating bar 18. All of the operating parts, exceptthe transom arm 7 and operating handle 55, are concealed from view sothat the appearance of the door or other casing is not marred.

While I have herein described the bellcrank 20 and its connections asfor a bottom hinged transom, it will, of course, be obvious that thespecific manner of connection may be modified to suit top and centerhinged transoms, the same principles of operation being involved in eachof these cases.

From the foregoing it will be obvious that th mechanism of the transomoperator, except such parts as of necessity are directly connected tothe transom itself, may be embodied in the form of an assembled unitmounted upon the frame or plate 1 ready for application to the jamb of adoor. It will also be obvious that the bell-crank lever 20 and therelatively eccentric lever formed by the arms 7 and 10 are soconstructed and arranged to afford maximum leverage to raise the transomfrom lowered position, and minimum leverage when the transom is inclosed position. In opening the transom, it is not necessary to employany great amount of leverage, as the opening action is usually aided bygravity. On closing the transom, however, the greatest load isencountered and I have so constructed and arranged the parts of mydevice that the maximum leverage is secured at the moment when it ismost needed. It will also be evident that while the invention has beenspecifically described as applied to transoms, it is of general use inconnection with various forms of hinged closures.

It should be understood that the arrangement of pin and slot connectionsshown may be reversed without departing from the spirit or scope of thisinvention, since the function of the pin and slot connections shown at6-8 and also at 1123 is simply that of well-known compensating means and1s used to permit that degree of independent movement required in thetype of compound or differential lever action shown.

lVhile I have herein described and illustrated a specific embodiment ofmy invention, it should be understood that the same may be altered indetail and relative arrangement of parts within the spirit of theinvention and the scope of the appended claims.
